AFAIK there is a patch in the works for all non-NA Xbox versions, to bring them up to the NA version number. Larian was waiting for the NA patch to clear to finalize and submit the other patches, presumably so that fix could be integrated as well. There have not been any updates on the progress, though.
I believe if the Xbox is online you should get automatically notified of an update when the game is started (once one is available).
